AISC — Wide Flange (I-beam)
Wide flange beams (W shapes / I-beams) are the most common structural steel profile used in building construction. They are used for beams, columns, and girders in steel-framed buildings and bridges. Designed per AISC 360, Eurocode 3, and NBR 8800.
The W250x33 steel profile weighs 32.7 kg/m (21.97 lb/ft), has a depth of 258 mm (10.16 in), flange width 146 mm (5.75 in). Cross-sectional area: 4,120 mm². Moment of inertia Ix = 4,818.22 cm⁴, Iy = 472.46 cm⁴.
